Specification of Letters Patent.

Patented April 30, 1907.

Application filed November 6,1905. Serial No. 286,160.

To all whom it may concern:

Be it known that I, RAOUL PHILIPPE, a citizen of the French Republic,residing at Paris, in the Department of the Seine, France, have inventedcertain new and useful Improvements in Prime Motors, of which thefollowing is a specification.

This invention relates to prime motors, propelled by either oil, gas,steam, compressed air or water under pressure. Its object is to enablesin le acting or double acting motors, with eit er one, two or fourcylinders, to be operated without connecting rods, or cranks, and atvery high speeds, giving a perfect rotary motion without thumps orvibrations when running. The same construction is capable of use as apump or a 1i uidmeter. Y

the accompanying drawings, Figure 1 is a transverse cross section of afour cylinder engine embodying my invention. Fig. 2 is a longitudinalcross section of a four cylinder engine having the cylinders set inpairs side by side, and Fig. 3 shows a further modification.

Referring first to Fig. 1, the four cylinders are shown located in thesame plane and spaced ninety degrees apart, concentric to the shaft e.In each cylinder is a piston, a, b, c, d. The pistons a, c, areconnected together by links h, which are slotted to let the shaft pass,through without interfering with the reciprocation of the pistons. The

, pistons b, d,.are similarly connected. On

the shaft, in line with the pistons, is keyed.

an eccentric g, and surrounding said eccentrio is a ring f mounted onball bearings so as to revolve easily thereon. The ring just fills thespace between the inner ends of the .pistons, whichv are wide enough toengage said ring at diametrically opposite points at all times. saidpistons in succession, they cause the eccentric to rotate and thus drivethe shaft.

In the modification shown in Fig. 2, the pistons b, (1, lie side by sidewith the pistons a, 0, respectively, and each pair of pistons'engagesits own eccentric. The two eccentrics are set quartering on the shaft,so that as the steam is admitted first to the two upper pistons and thento the two lower ones, the shaft will be given an impulse at eachquarterrevolution. r

Fig. 3 shows another modification in which the ring is omitted and theends of the pistons are provided with rollers 'i which bear directlyagainst the periphery of the eccentric.

Having thus described my invention what I claim is 1. The combinationwith a shaft, of a plurality of eccentrics secured thereon and setquartering, a ring concentric with each eccentric, balls between eachring and its eccentric, a pair of pistons bearing against each ring atdiametrically opposite points, and links connecting said pistons andprovided with slots for the shaft to ass through.

2. The combination wit a shaft, of eccentrics secured thereon and setquartering, a ring revoluble on each eccentric, a pair of pistonsbearing against each ring at diametrically opposite points, said pistonsbeing arranged in pairs side by side, and slotted links connecting saidpistons in each pair.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
